An example of a foliated metamorphic rock is a mica schist. //-->. Although non-foliated rocks may have small bands of different colors, the crystals that form them generally have no visible organization. Non-foliated metamorphic rocks such as quartzite and marble do not display the banding or layering that are present in foliated rocks. Non-foliated rocks form through recrystallization of single-mineral sedimentary rocks, usually those that have been touched by magma. Quartzite is made of metamorphosed sandstone, while marble is formed from limestone that was metamorphosed. Learn more. The pressure applied to the reforming rock causes the differences in the way the rock looks once recrystallized and determines whether it will be foliated or nonfoliated. The heat and pressure was relatively uniform from all sides. On the other hand, foliated metamorphic rocks have very obvious bands of layers that formed as a result of a more rapid cooling or higher pressure. - Definition & Example, What is Deformation?

A foliated metamorphic rock will have banded minerals. Non-foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non-layered or banded appearance. Sciences, Culinary Arts and Personal Metamorphic rocks occur when one of the other two types of rocks is subjected to such great heat and pressure that their chemical makeup actually changes. The minerals will appear to be randomly oriented without obvious banding and have a granular appearance. Hornfels have no specific composition while amphibolites are formed from hornblende and plagioclase. Different types of rocks and minerals can form non-foliated metamorphic rocks.

Some rocks, including limestone are product of minerals that aren’t flat or elongate. Non-foliated metamorphic rocks do no longer have a platy or sheet-like shape.
